The OpenGL Samples Pack 4.3.2.0 mainly adds MacOS X support through a set of 27 OpenGL 3.2 samples and it restaures Linux support. This has been made possible by replacing FreeGLUT by GLFW and removing GLEW which doesn’t support the core profile. The 27 OpenGL 3.2 samples are essentially back port of previously OpenGL 3.3 samples.
